I am trying to connect source and destination points with the hub lines tool in mmqgis. I have gone through the other posts on this subject but couldn't figure out what I am doing wrong. I have succeeded doing so before in a different school project and I can't understand why it is not working now. The tables have pretty much the same fields as the last time. the 2 tables are the same, but saved once as source and once as a destination. I will add screen shots of the fields and the hub lines application window and maybe someone will see what am I doing wrong.
